I tested the new version, and started a session, and spoke 20-30 words.

I stopped the session.

I started a new session.

In the client web site, the words from the previous session were still there. The top words started to get replaced initially, and so there was a strange mix of words from the current and previous session. After 10-20 seconds, the words from the new session started to appear at the bottom of the words from the old session, so it got even stranger. After a minute or so, all the old words from the old session would have floated up and out of view, so it's not a big deal, it's just strange.
